Can someone check their 240v charger for the Coleman Hot Water on Demand and tell me what specs and markings are on it as i have numerous chargers here and the battery is a 6V baby. The charger i have for it outputs 12V 700mA ~ and just need to confirm it is the right one. :)

I can't find the thread on EO when this was last talked about...i vaguely recall having a contribution to it, though i'm sure Kev the Search engine can find it in 2 minutes LOL.

Thanks in advance

Andrew

Andrew, I don't have one of these but from what I read on the Coleman site the unit has a 6 volt SLA battery and must have an in-built charge controller as it is specified to be able to be charged either from the car's 12 volt or from the 240v mains via a supplied 240vac to 12vdc 700mA module. The necessary cables are supplied with the heater.

So I would believe that the 12v 700mA charger you have would be the correct one. The instructions are to recharge each six months.

Cheers
Allan

Thanks Allan, i didn't see that on my quick search :(

Those little SLA batteries sure hold their charge well surprisingly, can't remember the last time i charged it. :)

Be very wary. At least some are different.

The Coleman 240 volt adaptor with mine is an AC to AC adaptor.

Specs and model numbers as per Sir Kev except the output is AC. IT REALLY IS AC. Confirmed by a Fluke T5-600.

Now this is one of those weird things in electronics because the socket that it plugs into will also accept 12v DC input. Coleman supply a lead for this with the unit.

The danger is that all 240 volt adaptors look pretty much alike and can get mixed up. Do not plug the Coleman 240 volt adaptor into something that requires DC only. You may cook it. I did that once to my cost. Now the plug pack is stored with the HWOD at all times and is never stored with other generic plug packs.

Funny thing was I had the Fluke at the time but assumed the plug pack output was DC.

Thanks for the warning Flynnie, that is the reason i asked the question in the first place ;) They must rectify in the unit for the charging component i summise.

Does this mean you cannot wire up a direct line to a 6 volt deep cycle battery/
As I have 2 x 6 volt trojans I was going to wire it direct to one battery.

Just don't wire it up to the socket on the side of the unit as i would imagine any rectification and/or diode arrangements wouldn't allow for adequate charging voltage. Wire in a different socket that goes straight to the battery terminals would work in a basic manner, however i don't see a huge need for an additional battery for this system as the small 6v one seems to do the job ok in most cases. :)

....or straight across the 12v arrangement :)
